Abstract : The cyclotron, an improved version of the Oak Ridge Isochronous Cyclotron (ORIC), will furnish large ion currents (up to 1 mA) with variable energy (from 5 to 75 MeV for protons), and a large choice of ion species for research in nuclear physics. The magnet gap of the NRL cyclotron has been changed from the vertical plane used in the ORIC to the horizontal plane because an analysis indicates that there will be a large improvement in the intensity of the energy-analyzed beam. This and other changes based on operating experience at the ORIC were incorporated in the scope of work given to the engineering firm who prepared bid packages, and assisted in the procurement of components, and in the critical path management scheduling of the cyclotron program. An automated system, utilizing a Hall-plate which is positioned by a tape-controlled table, has been developed to map the magnetic field of the cyclotron. Computational techniques have been developed for analysis of various ion-optic problems. Preliminary analysis of the combination of an energy-analyzing magnet, switching magnets, and quadrupoles has been performed so that the beam can be brought into any one of eleven proposed beam paths. Detailed design of three beam paths which will be instrumented initially has been completed. A major feature of the cyclotron beam-transport system is an 80-ton, 135-degree, 9-ft-radius energy-analyzing magnet which has an energy resolution better than 5000. (Author)
